To all whom it may concern,.- secure the full throw of the lamps and blade,

Be it known that I, CHARLES R. JOHNSON, and as a locking-plate in connection with the of the city and county of New York, in the arm e in addition to its function as a means State of New York, have invented a new and for transmitting motion from the weighted 5fuseful Improvement in Railway-Signals, of lever E to the operating-rod O. To this end 55 which the followingI is a specification. the plate is provided with a recess d, adapted My invention relates toan improvement in to receive a stud or roller d on the end of railway-signals in which several lights are so the arm c, and said recess d is provided with arranged with respect to the signal-arm. and 'a flaring mouth, the jaws cl2 of which are ro its operating mechanism that they will show adapted to rest upon the stud or roller d on 6o different series of lights of different colors the end ofthe arm c when the leverE is tilted when the signal is set for danger and for in the one direction or the other, and the presssafety. ure upon the arm c when it is engaged with My present invention more particularly conone of said jaws d2 will be in such a direction l5 templates the employment of three lights in that the plate D cannot be swung by manipu- 65 connection with the signal-arm and its operatlating the rod C, but. may be readily swung by ing mechanism so arranged that there may be manipulating the weighted lever E. Theseats shown two lights of one color in a horizontal for the stud or roller d allow thearm e to swing series or two lights of another color in a vera short distance without eiiecting the movezo tical series, according as the signal is set for ment of the plate D, its complete throw being 7o danger or safety. insured before the roller d engages the seats A practical embodiment of my invention is upon the Haring jaws. The plate D thus represented in the accompanying drawings, serves to lock the signal-arm B securely in its in whichposition, while at the same time it provides 25 Figure l is a view of the signal in front elcfor lost mot-ion, and is free to be manipulated 75 Vation showing the position of the parts when by the movement of the lever E under the set for danger, and Fig. 2 is a transverse strain of either one of the connections c. section through the signal-post, showing a top A lam p-F is located upon a fixed support f plan View of the horizontal series of lights in such position that the disk b on the signal- 3o and their supporting and operating 1nechanarm support will fall in front of it and ob- 8o ism. scure it from view when the signal-arm B is A represents the signal-post provided near set for danger, as shown in Fig. l, but will its top with a vertically-swinging signal-arm lift from in front of it and expose it to view B, `pivotally secured to the post and operated, when the said signal-armis dropped into the 35 asis common, by a rod O, connectedtherewith position of safety. 85 andextendingalongdowntheposttotheswing- Suitable supporting-brackets G and G are ing operating-plate D, to which it is also con xed to and extend laterally from the post A nected at a point to one side of the pivotal at a point below the lamp F, and are proconnection of the plateD with the post. The vided in their outer ends with sockets g g',

4o plate D is in effect an angle-lever, the operatrespectively, in which are seated rotary lain ph 9o ing-rod C being connected to one arm of the supports 7L and 7L. Fixed to the rotary suplever and the other arm of said lever being ports h and 7L', respectively, are lamps H and operated by an arin e, fixed to a weighted le- I-I, the former provided with two lensesIand ver E, pivotally secured to the post and havt and the latter with a single lens I. The

45 ing attached thereto upon opposite sides of lenses I and t' of the lamp II are preferably 95 its pivotal connection chains or other suitable located at a quadrants distance apart in its operating devices which connect with a suitperiphery, so that, supposing the lenses I to able operating device (not shown) at the stabe toward the front, a quarterturn of the tion from which the signal is to be manipulamp will bring the lens t' to the front.

5o lated. The plate D is utilized, however, to The supports 7L and 7L are provided at their roo lower ends, below the sockets g and g', with crank-arms 7a2 and h3, the ends of which are connected with a bar K by links 7s and 7c.

The particular means which I have adopted for connecting the links 7a and 7c with the ber K in order to render them adjustable with respect thereto are as follows: The ends of the bar K are bifurcated, and the perforated heads of bolts k2 and k3 are secured in the bifurcated ends of the bar K by pivot-pins, while the threaded ends of thebol ts are screwed into the ends of the links 7.; and 7c', and are locked therein by jam-.nuts 7a4 and h5. An angle-lever is pivotally secured to the front of the post and has one of its arms L engaged with a stud 7.36 on the b ar K and its otherarm Zconnected with the operating-rod C. Provision is made for the circular path of the end of the arm L of the lever by providing it with an elongated slot Z for the reception of the stud k6. The connections of the arms L and Z of the angle-lever with the bar K and operating-rod C are so located that when the operating-rod C is depressed to set the signal to danger the lamps upon the rotary supports h h will be rocked into position, as shown in Fig. l, to present theirlenses I I to the front. Suppose the lenses I and I to be of the same color-as, for example, red-and the lens rof the lamp Hand the lens of thefixed lamp F be green. Vhen the signal is set for danger, there will appear two red lights in horizontal alignment, as shown in Fig. l, and when the signal is set for safety there will appear two green lights in vertical alignment, for the reason that the upward thrust of the operatingrod C will reveal the green light in the fixed lamp F, as hereinbcfore set forth, and will at the same time rotate the lamps II and H', so as to throw the lenses I and I off to one side out of view and at the same time bring the green lens z' into View at the front and in vertical alignment with the lens of the lamp F.

By the above simple arrangement I am enabled by simply mounting the two lamps H and H upon rotary supports and connecting them with the rod C to present a two-light signal for safety or danger, which shall not only vary in color, but also in position. It will be observed that the construction and arrangement of parts is such that the lamps may be readily attached to the signals in common use without any substantial modification of their parts.

l. The combination, with a horizontal series of rotary lamps and a vertical series of lamps, one lalnp being common to both the horizontal and vertical series, of a signal-operating rod, and intermediate mechanism between the rod and lamps, whereby the lights from the horizontal series of lamps are exi posed when the signal is thrown in one direction and the lights from the vertical series of lamps are exposed when the signal 1s thrown in the opposite direction,substantiall y as set forth.

2. The combination, with a horizontal series of rotary lamps and a vertical series of lamps, one of the lamps of the horizontal series forming, also, one of the lamps of .the Vertical series and another lamp of the v ertical series being fixed, of a signal-operating rod, a shield connected therewith and adapted to obscure and expose the fixed light as the rod is thrust in one direction or the other, and a connection between the signal-operating rod and the series of rotarylamps, whereby the latter are rocked in one direction or the other as the rod is thrust in the one direction or the other, substantially as set forth.

3. The combination, with the signal-support, the signal-arm pivotally secured thereto and provided with a disk or shield, and a signal-operating rod for operating the signalarm, of a lamp fixed in position to be exposed and obscured by the disk carried by the signal-arm, a pair of lamps having rotary supports and located in horizontal alignment, cranks secured to the rotary lamp-supports, a bar connected with the cranks, and an anglelever engaged with the connecting-bar and signal-operatingrod, whereby the lamps in horizontal alignment are simultaneously rotated as the signal-operating bar is moved, substantially as set forth.

4. The combination, with the rotary lamps in horizontal alignment, one of the lamps being provided with lenses of different colors facing in different directions, and a fixed lamp located above the rotary lamp with the different lenses and having a lens corresponding to one of the lenses on the rotary lamp, another lens on the rotary lamp corresponding with the lens upon another rotary lamp in horizontal alignment therewith, of a signaloperating rod, mechanism connecting the signal-operating rod and the rotary lamps, and.

a shield connected with the operating-rod in position to obscure and disclose the light from the fixed lamp, the shield and the rotary movements of the lamps being so timed that when the operating-rod is thrust in one direction lights of the same color will be exposed to the front in the rotary lamps and the light ot' the fixed lamp obscured and when thrust in the opposite direction lights of the same color different' from that before exposed will be disclosed from the fixed lamp and one of the movable lamps in vertical alignment therewith and the two previous lights obscured from the front, substantially as set forth.
